CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 565,977, dated August 18, 1896.

. Applicationiiled March 19,1896. Serial No. 583,914. (No model.)

To all whom, t may concern:

Be it known that I, SIMON GRENIER, a citizen of the Dominion of Canada, residing at St. Csaire, in the county of Rouville and Province of Quebec, Canada, have invented certain new and useful Improvements in Car-Couplin gs and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

This invention relates tocar-couplings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side View of the car-coupling. Fig. 2 is a sectional plan View of thesame.

Both halves of the coupling are alike, and they are connected together by a long link A.

B is a block carried by the draw-head C of the coupling. The block B is rectangular and slides longitudinally ina socket in the draw-head C. The block B is provided with a stem h, and b is a spring which encircles the stem b and presses forward the block B in the socket. The front end of the block B is provided with a jaw c, adapted to engage with the end of the link, and the front end portions of the jaw andthe front portions of the draw-head C have beveled guide portions c', so that the end of the link may be guided into the jaw when the halves of the coupling are pushed together.

D is a vertical pin which is slidable in a hole in the draw-head C, and CZ is a spring which presses the said pin downward. The top of the spring is secured to the top of the pin and the bottom of the spring is secured to the draw-head. The spring is under tension when it is raised, so that it tends to propel the pin downward. This pin, when in a raised position, is supported by the front end of the j aw c, as shown at the left-hand part of Fig. 1. lVhen the other half of the coupling is moved in the direction of the arrow, the front end of the link enters between the jaw, pushes the block back against the pressure of the spring b', and permits the pin to be propelled downward through the link into the position shown at the right-hand part of Fig. I, thereby coupling the two halves of the coupling together.

What I claim is- In a car-coupling, the combination, with a draw head C provided with a rectangular chamber; of a rectangular block B slidable in the said chamber and provided with a stem h slidable' in a hole at the rear of the chamber, and a jaw c at its front end; a spring b encircling the stem b and pressing forward the said block, a link supported by the said' jaw in a substantially horizontal position, a vertical pin D normally resting on the front end of the said jaw and slidable in holes in the draw-head, and a spring d having its upper end secured to the head of the pin and its lower end secured to the draw-head, whereby said pin is forced downward through the said link when the said block is pressed back, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SIMON GRENIER.
